As paintball technology gets better, the tanks get lighter. Empire is proud to announce their Ultra Tank, this tank is a 68 cubic inch carbon fiber tank, with a 4500psi capacity. What sets this bottle apart from almost all other paintball air systems is how light it is, weighing in less than two pounds. The Ultra features a regulator that uses the same technology as the tried and true Pure Energy regulators. This tank is manufactured in the United States, and has a five year hydro date.
